The issue that has bugged (hah!) me the most about Waze is that I'll establish the trip while in my driveway, but between parked and getting on the road, Waze will recalculate the route, possibly multiple times. This is particularly annoying when I've already accepted one of the alternate routes, and now while in traffic have to reselect it. Other nav programs say things like "Proceed to the route" or even better "Begin on X street southbound" but Waze just goes bonkers. Now I navigate with Apple (if it knows the destination) or Google (knows many more destinations than Apple), but only use Waze for notifications on the highway.
It's good that this is available for those who don't use CarPlay, but lame that it's only Apple Music the service and not access to your music library in general.
